1'0 all whom, it may concern.-

Be it known that I, CARL F. BUSCHNER, of New York cit-y, New York, haveinvented an Improved Oar-Truck, of which the following is aspecification.

This invention relates to a cantruck provided with an anti-frictionbearing of simple construction.

It consists in the various features of improvement, more fully pointedout in the claims.

In the accompanying drawings, Figure 1 is a side View, partly insection,of myimproved car-truck. Fig. 2 is a front view, partly insection, of the same; Fig. 3, a top view of the truck, and Fig. 4 a topview of the equalizing-bar b.

'The letters a a represent the longitudinal timbers of the truck-frame,and b b are the equalizing-bars.

c o are the interposed spiral or gum springs, and c an additionalsemi-elliptic spring.

(Y represents the axles ending in journals (1, that are received by theslot-ted hangers (1 Above the journals d the timbers a are slotted, asat a, and to the right and left of the slot the timbers are providedwith an upwardly-projecting semicircular cheek a lVithin the slot a andbetween the cheeks a there is placed an anti-friction disk or wheel 6,against which the journal (1 bears directly. The disk e is provided withjournals e',which are engaged by the hook-shaped ends b of theequalizing-bars I). These ends Z) are slotted, Fig. 4, and are bentfirst upward and then downward, Fig. 1, so as to straddle or embrace thedisks e to form the bearings for the journals e.

in use the revolution of the axles (1 will cause the journals cl toslowly revolve the disks 6 between the cheeks (1 The journals 6' ofthese disks revolve in the hook-shaped ends of the equalizing-bars b,and thus a simple and effective bearing is provided.

WVhat I claim is- 1. The combination of slotted timbers a, withequalizing-bars I), having slotted ends I), anti-friction disks 6,embraced by and turning in said ends and axle-journals cl, engaging saiddisks, substantially as specified.

2. The combination of slotted timbers n, having upwardly-projectingcheeks M, with equalizing-bars I), having slotted hook-shaped ends I),anti-friction disks 8, having journals 6', that turn in such ends, andwith axle-journals d, that engage disks e, substantially as specified.
